Epitaxially Integrated Electro‐Optic KNbO 3 Thin Films on Silicon

ABSTRACT The absence of a native electro‐optic effect in silicon remains a fundamental limitation for integrated photonics, motivating the integration of ferroelectric oxides as active materials. Here, we report the first epitaxial integration of KNbO 3 thin films on silicon, est...

Dynamics of a jointly commensurate moiré charge density wave

Abstract The advent of two-dimensional moiré systems has revolutionized the exploration of phenomena arising from strong correlations and nontrivial band topology. Recently, a moiré superstructure formed by two coexisting charge density waves with slightly mismatched wavevectors...
